The grant landscape for solar panels in Scotland has changed significantly over the past two years. The Home Energy Scotland Solar PV grant, which provided up to £2,500 for eligible homeowners, closed to new applications in June 2024. ECO4, the energy efficiency scheme that funded solar and insulation measures for lower income households, ended in March 2026. For homeowners researching solar in 2025 and 2026, the question is what financial support actually remains.
This guide sets out the current position clearly: what has closed, what is still available, and how to make solar financially worthwhile in the current funding environment.
What has closed: the Home Energy Scotland solar grant
Home Energy Scotland is the advice and grant service run by the Energy Saving Trust on behalf of the Scottish Government. Until June 2024, it offered a grant of up to £2,500 toward solar PV installation for owner occupiers and some landlords.
The grant was conditional on the property meeting a minimum energy efficiency standard and was administered through a survey and approval process before installation. It significantly improved the financial case for solar for eligible households.
The grant closed on 30 June 2024 when the Scottish Government redirected renewable energy funding toward the Warmer Homes Scotland programme and the emerging Warm Homes Plan. There is no current indication that the solar PV grant will reopen in its previous form.
What has closed: ECO4
The Energy Company Obligation scheme (ECO4) required large energy suppliers to fund energy efficiency measures for eligible low income and vulnerable households. Solar PV was included as an eligible measure in ECO4 for households meeting the income and property criteria.
ECO4 ran from April 2022 to March 2026. The successor scheme, ECO5 or a replacement under the Warm Homes Plan, had not been confirmed for Scotland as of April 2026.
What is still available: 0% VAT on solar and battery storage
The single most significant financial support for solar in Scotland in 2025 and 2026 is not a grant. It is the 0% VAT rate on solar panel and solar battery storageations, which applies automatically to all qualifying residential installations in the UK.
Prior to April 2022, solar installations attracted 5% VAT. The rate was cut to 0% as part of the government’s response to rising energy costs and remained in place when it was reviewed in 2023. The 0% rate is confirmed until at least March 2027.
The saving is meaningful in practice. On a typical Aberdeenshire solar installation costing £7,000, the standard 20% VAT rate would add £1,400. The 0% rate means you pay £7,000 rather than £8,400. On a combined solar and battery system costing £11,000, the VAT saving is £2,200. This automatic VAT relief is the equivalent of a grant for every homeowner, not just those who qualified under the previous income criteria.
Battery storage installed at the same time as solar panels attracts the same 0% rate. A standalone battery retrofit (added to an existing solar system without new panels) may have a different VAT treatment depending on the specifics of the supply, but Faithful Spark confirms the VAT position in every quote.
What is still available: the Smart Export Guarantee
The Smart Export Guarantee (SEG) is not a grant, but it is a genuine financial return on solar investment. Under the SEG, electricity suppliers with more than 150,000 customers are required by law to offer at least one tariff that pays homeowners for surplus solar electricity exported to the grid.
SEG rates from major suppliers in 2025 and 2026 range from approximately 3p to 15p per kWh. Some specialist tariffs, including dynamic tariffs linked to wholesale electricity prices, offer higher rates at certain times.
To access SEG payments, the installation must be carried out by an MCS NICEIC Approved Contractor and registered on the MCS database at completion. The homeowner applies directly to their electricity supplier using the MCS certificate to begin receiving export payments.
For a 4kWp system in Aberdeenshire exporting 800 to 1,200 kWh per year at an average SEG rate of 14.5p, the annual SEG income is approximately £56 to £84. Small in isolation, but over a 25 year system lifetime the cumulative SEG income is £1,400 to £2,100. For our guide on maximising SEG income, see our page on the Smart Export Guarantee in Scotland.
What may be available: the Warm Homes Plan
The UK Government’s Warm Homes Plan is the successor to ECO4 and the previous Home Upgrade Grant. It was in development during 2025 and 2026 with the aim of providing funding for low carbon heating and energy efficiency measures for owner occupiers and private renters, with a particular focus on lower income households.
As of April 2026, the detailed eligibility criteria, funding levels, and delivery mechanism for Scotland had not been confirmed. The Scottish Government administers energy efficiency funding separately from England and Wales, so the specific terms for Scottish homeowners will be set by the Scottish Government when the scheme is finalised.
Solar PV is expected to be an eligible measure under the Warm Homes Plan for households that meet the income threshold. If your household income is below approximately £36,000 per year or you receive certain means tested benefits, it is worth checking your eligibility before proceeding with a funded installation. Faithful Spark can advise on current eligibility at the survey stage based on the most recent confirmed scheme details.
What is still available: Home Energy Scotland interest free loans
While the Home Energy Scotland grant for solar PV has closed, the interest free loan component of the Home Energy Scotland offer continues. Home Energy Scotland offers interest free loans for certain energy efficiency and clean heating measures.
The loan scheme is administered by the Energy Saving Trust on behalf of the Scottish Government. Loan amounts and eligible measures are subject to change and depend on your property type, tenure, and the measures being installed. As of early 2026, loans were available for heat pumps and some associated measures. The position on solar PV loans should be confirmed directly with Home Energy Scotland at the time of enquiry on 0808 808 2282.
Does solar still make financial sense without the grant?
Yes, for most Aberdeenshire homeowners. The grant made a good investment better. Without it, the financial case is slightly longer to pay back but still clearly positive over the 25 year system lifetime.
The key factors that determine financial viability are the electricity rate you are paying, the proportion of solar generation you consume directly within the home, whether you add battery storage, and your expected electricity price trajectory over the next decade.
At current electricity prices of around 24p per kWh, a 4kWp system in Aberdeenshire with battery storage saving approximately 2,200 kWh per year returns £528 per year in bill savings alone. Against an installed cost of £10,000 to £12,000 for a combined solar and battery system with 0% VAT, the payback period is 19 to 23 years. Without battery storage, the payback on a £7,000 system is 14 to 18 years. These are the upper bounds. With time of use tariff optimisation or rising electricity prices, which most analysts expect over the 2020s, the payback shortens considerably.
The Home Energy Scotland grant shortened the payback by 2 to 4 years for eligible homeowners. Its absence lengthens the payback period back by the same amount. The underlying investment remains positive.
Frequently asked questions
Will the Home Energy Scotland solar grant reopen?
There is no confirmed date for the solar PV grant to reopen. The Scottish Government has indicated that clean heat and energy efficiency funding will be channelled through the Warm Homes Plan going forward, with the specific design and eligibility criteria for Scotland still being developed. Faithful Spark will update clients on any new grant availability as details are confirmed.
Can I apply for ECO4 funding for solar?
ECO4 ended in March 2026. Applications are no longer being accepted. The successor scheme, likely ECO5 or the Warm Homes Plan equivalent, had not been launched for Scotland as of April 2026.
How do I claim the 0% VAT on my solar installation?
You do not need to do anything. Your installer applies the 0% rate at the invoice stage. Faithful Spark’s quotes show the price inclusive of 0% VAT on eligible items. You pay the quoted price with no additional VAT on top.
Is there any difference for landlords versus owner occupiers?
The 0% VAT rate applies to both. The Home Energy Scotland solar PV grant that closed in June 2024 was available to owner occupiers and some social landlords; landlord electrician Aberdeen were generally not eligible. The Warm Homes Plan may include provisions for private rented properties, but details for Scotland had not been confirmed at the time of writing.
Does my income affect whether I qualify for any support?
The 0% VAT and SEG are universal. The Warm Homes Plan, when launched, is expected to be means tested with higher support for lower income households. The Home Energy Scotland advice service at 0808 808 2282 is the right first contact for income related support and loan eligibility.
